Do you know the method used to detect: coagulase, hemolysin, DNase, lipase, and gelatinase?
Coagulase- A suspension of the test organism in citrated plasma is prepared and the inoculated plasma is then periodically examined for fibrin formation, or coagulation.
DNase- test oraganism is grown on an agar medium containing DNA. Following incubation, DNase activity is determined by the addition of 0.1% toluidine blue to the surface of the agar
